DEVICE FOR LOADING AND UNLOADING CARS.

SPECIFICATION forming part of Letters Patent No. 325,309, dated September 1, 1885.

Application filed July 2Q. 1355. (No model.)

To @313 whom it may concern.-

Be it known that we, HENRY M. BARN'HART and EDW'ARD HUBER, of Marion, in the county of Marion and State of Ohio, have invented certain new and useful Improvements in Deviccs for Loading and Unloading Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

Our invention relates to an iinprovemcntin a device for loading and unloading cars, the object of the same being to provide a device whereby a train of platform-cars can be loaded or unloaded by a movable device carried on the cars and adapted to travel from car to car; and with these ends in view our invention consists in the combination, with a train of platfornrcars, of a sled or frame mounted on said cars and carrying a crane, and devices connecting the sled and cars, whereby the former can be moved from one end of the train to the other end.

Our invention further consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a viewin side elevation showing ouriinprovemcnt applied to a train of platformcars. Fig. 2 is a plan view of the same.

A represents a train of platfornrcars, each of which latter is provided on its opposite side edges with the upwardly-projecting guides B, which latter can be provided with rollers or not, as desired, and can be removed from the cars when not needed.

0 is a sled or carriage formed of a series of beams or runners, a, connected together by cross-braces a, and provided at one or both ends with the rigid loops 1), to which the tackle for sliding the sled from car to car is attached. The sled thus formed is preferably about as wide as the car-platforms, and is provided with the beveled ends, as shown, which permit the sled to slide from one car to another without liability of becoming wedged. This sled rests solidly on the platforms, and is provided on its'upper surface with a circular track having a fiat surface and a toothed perimeter,on which the crane or derrick frame rests. This frame consists, essentially, of a base, I), and a top, 0, connected together by suitable uprights, d, and braces 0.

At one end of the base bis pivotall y mounted the boom F, the upper end of which is supported by one or more tie-rods, E. This boom is adapted to carry an excavator, F, or block and tackle for elevating and lowering crossties, rails, and other articles. This excavating or hoisting tackle is operated by the rope or chain G, the inner end of which is secured to the windlass H, mounted in bearings secured to the derrick-frame. Alongside of the Windlass H is located the win'dlass H, to which is secured a rope or chain, by which the sled is moved. This rope or chain passes from the windlass upwardly over a pulley, f, thence downwardly in or nearly in a line with the axis of the derrick-frame,and around the pulley g,secured to the sled, then forwardly to a pulley secured to one of the cars, and then rearwardly to the rigid loop on the end of the sled.

The windlasses are operated by the engine I, which latter takes steam from the boiler, preferably located on the end of the frame farthest from the derrick. This engine is connected with both windlasses, and the latter are provided with clutch or other mechanism whereby either Windlass can be thrown out of engagement with the engine, as necessity demands.

The derrick-frame is pivoted to the sled in a vertical line passing through the center of the circulartrack,and is provided with rollers, which latter rest on the upper smooth surface of the circular track and form bearings for the derrick-frame. This frame is also provided with pinions, which latter engage the teeth on the perimeter of the circular track for the purpose of changing the position of the derrickframe, so as to bring the derrick from one side of the car to the other. These pinions can be operated by hand-Wheels or by the engine. The derrick can also be turned by the engine or by suitable devices operated by hand.

By the above arrangement of parts it will be seen that the sled carrying the derrick can be drawn away from the cars as the latter are loaded, and the cars can be drawn toward the material to be loaded. hen unloading, the derrick or crane can be drawn toward the cars to be unloaded.

Then the machine is employed for clearing the side of a track or widening cuts alongside of a railroad-track, an ordinary excavator would be employed, and the material as it is excavated would be dumped on the ears. When the device is employed for loading and unloading other material-such, for instance, as stone, timber, or railsthe excavator would be removed and block and tackle substituted.

It is evident that numerous slight changes might be resorted to without departing from the spirit of our invention; hence We would have it understood that we do not limit our selves to the exact construction herein shown and described; but,

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a device for loading and unloading cars, the combination, with a train of platform-cars, of a sled or carriage, a crane or derrick mounted on said sled or carriage, and devices, substantially as described, for moving the sled or carriage.

2. In a device for loading and unloading cars, the combination, with a train of platform-cars and a sled adapted to move on said cars, of a derrick-frame pivoted to the sled, a motor mounted on the sled, and devices connecting the motor and car, whereby the sled can be moved from one end of the train to the other, substantially as set forth.

3. The combination,with atrain-of platformcars, each of whichllatter is provided with side guides, of a sled adapted to travel over said cars and carrying a crane or derrick, and devices carried by the sled and connected to one of the cars for moving the sled, substantially as set forth. 7

4. The combination, with a sled or carriage mounted on platform cars, a derrick-frame pivoted to said sled, and a derrick or crane secured to said frame, of the devices, substantially as described, for moving the sled, substantially as set forth.

5. The combination, with a train of'cars having side guides, of a sled or carriage having beveled ends, a derrick secured to said sled, a carriage, and devices, substantially as described, for moving the sled.?

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
